HUMIDIEYING- DEVICE.

To all whom it may concern: o

-' Be it known that I, Vrcron- A. LARSoN, a

citizen ofthe United States, and a" residentof Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Humidifying Devices, of which v I c i I c My inventlon 1s an Improvement -1n huthe following is aspecificamidifying devices, and has for its object to .provide a device of the character. specified especially adapted for use with radiators of steam and hot water heating plants for humidifyin the air heated by the r adlator, wherein a evice is provided which may be .easily placed and removed, and which will thoroughly moisten the heated air rising from the radiator. 4

In the drawings: Figure 1 is a perspective view of-the device in place; v

Fig. 2 is a longitudinal vertical section; Figs. 3 and 4 are sections on the lines 3 -3 and 4-4, respectively, of Fig. 2, each new looking in the direction of the arrows ad-,

jacent to the line;

Fig. 5 is a perspective view of one of the wick supports; p

Fig. 6 is a perspective view of the device, with the cover removed.

The present embodiment of the invention is shown in connection with a radiator 1 of ordinary type, and the humidifying device is seated upon the top of the radiator. The said device. comprises a trough 2 of a size to extend approximately the full length of the radiator and of a Width somewhat. less than the Width of the radiator, the trough being adapted to seat upon the top of the radiator, as shown in Figs. 2 and 3.

This trough is adapted to contain water, and a casing is arranged over and above the trough, to cover the same. This casing consists of a body and a perforated top, the body being a substantially rectangular frame consisting of sides 3 and ends 4, and it will be noticed, referring to Fig. 6, that the ends are cut away at their lower edges to approximately half the height of the sides, and that the said ends have a flange 5 extending above the upper edges of the sides, the corners of the flanges being rounded. This body 3 is adapted to fit about the top of a radiator, with the lower edges. of the ends 4 resting upon the endmost sec- Specification or Ietters latent.

tions of the radiator, and with the said ends f the ends 4, to rest uponthe said ends,

with the edges of the cover contacting with.

the upper body.

:A pair of bars or edges of the side walls 3 of the ody, the said plates being secured to the ends 4 and being spaced as shown, "and from the ad acent side Walls. 1n .placein any suitable or desired manner, and a wok support is supported by each plate. Each of these" wick supports, as shown in Fig. 5, is composed of wire of suitable gage bent to form, and consists of three lates 7 is arranged Theplates are held longitudinally extending members 8 and 9, i

and angular end members 10 connecting the longitudinally extending members. 1

The longitudinally extendlng members 8 are at the ends of the angular end members 10, while the member 9 connects the angles of the said members 10. Thus a skeleton frame is formed of angular shape, consistmg of two portions having-their planes at right angles, and these supports are supported .by'the said plates 7. i

One of these portions rests upon the bar or plate, with the other portion depending into the trough 2, and a wick 11 is supported by each of the said supports. The wicks are endless belts, passing around the members 8 and 9 ofthe frames, and the lower run is held in place by the perforated plate 7. The wicks depend into the water in the trough.

In use, the device is arranged as shown in Figs. 1 to 3, inclusive, the trough 2 being seated on the radiator section. The body 34 is then placed, after'which the wick supports with the wicks in place are arranged'on the plates 7. When now the cover 6 is placed in position the device is ready for operation. The heated air rising upwardly.

from the radiator passes through the body of the casing and is thoroughly moistened by the water held on the wicks, passin out eventually through the perforations 0 the porting thewick supports, hold the under portion of the wick taut and in angular posltion as shown in Fig. 3. The water passes up the wicks by capillary attra'ction'continuously and continuously evaporates so long as there is water in the pan. In hard water, when the portion of the wick exposed to the air becomes clogged by deposits the wick may be moved to bring another part into contact with the water, where. the deposits are redissolved. l p

I claim:

1. A device of the character specified, comprising in combination with a radiator, a trough adapted to seat upon the top of the radiator, a casing comprising a body frame open at its top and bottom and fitting over the trough, the sides of the body depending below the ends to permit said sides to extend below the bottom of the trough when the endsengage the top of the radiator, and a perforated cover resting upon the top of the body, said trough being adapted to contain water and the body having bars extending above the trough at each side of the center thereof, and wick supports upon the bars, each support carrying a wick and holding a portion of the wick in the water in the trough, each Wick being in the form of an endless band mounted to move on the spring to bring different portions of the wick into contact with the water, each support having a skeleton frame having two portions extending at approximately right angles with respect to each other, one of the said portions resting upon the bar and the other depending therefrom.

'2. device of the character specified, comprislng'a trough adapted to seat upon the top of" a radiator, a casing comprising a body frame open at its top and bottom and depending below the ends to permit said sldes. to extend below the bottom of the trough when the ends engage the top of the radiator, and a' perforated cover resting upon the top of the body, said trough being adapted to contain water and the body having bars extending above the trough at each side of the ,center thereof, and wick supports upon the bars, each support carrying a wick .fitting over the trough, the sides of the body and holding a portion of the wick in the of the radiator when the ends engage the top thereof, wick supports carried by the casing, and wicks on the supports depending into the trough.
